For being a gas hog, I think the 68 Special beats them all. In small fields the beast is cumbersome weighing in at 6 pounds empty, it's definitely handicapped. But in Miami we played large fields where you could wait 5 to 10 minutes before seeing an enemy. Before HP and backspin barrel attachments, the 68 was The range gun. Paint was not round and all markers fired the first shot the same distance. Follow ups by the other markers would rapidly fall short on volleys, with only the first shot in range. The siphon fed 68 Special maintained its maximum range throughout the volley and could be zeroed on target. We had two 68 Specials with sniper barrels on our team and we always played right and left rear guard. In rapid shot firefights we could even fire over our front line and engage the enemy while staying out of range and not dropping on our own players. With the clank and dry ice, it's still my favorite despite the lack of big playing fields now.
It's a Tippmann 68 Special, Why would I need anything else...and don't rush a Tippman gun fart, My Puma bites.
